Hi James, I'm still planning at looking at this, but sadly I didn't have the time. Also, every time I ask where are the HATEOAS clients, the only reply I get is that people only use it for "inside apps". The only time I saw something similar to HATEOAS that is actually used and public is the CMIS standard.
I still think it's doable to build responses in HATEOAS by adding a reader and a writer to ERRest (.atom for the extension) but beside building it for learning, I don't see a need unless intelligent clients can use it. > I am curious to know whether anyone has used ERRest to build a REST API that > fulfills the HATEOAS part [1](hypermedia as the engine of application state) > of the REST architectural style.
